Cell and Its Environment

Which of the following processes takes place when a plant cell is put in a hypotonic solution?

  1. A.Water moves into the cell and the cell bursts
  2. B.Water leaves the cell and the cell becomes flabby
  3. C.Water moves into the cell and the cell becomes turgid
  4. D.The cell becomes plasmolysed

Answer: C (Water moves into the cell and the cell becomes turgid)

Explanation

Water enters by osmosis, but the strong cell wall stops the plant cell from bursting, so it becomes firm (turgid).
